This article describes the procedure to install Debian on a Linkstation Pro or Kurobox Pro by creating a minimal installation on a Linux workstation and transferring it to a Linkstation. Access via serial cable is not required.

Prerequisites

To run this procedure you will need a computer with some form of Linux installed on it, preferably Debian or a variant of it such as Ubuntu. The CPU architecture isn't relevant, so if you have another Linkstation with Debian on it that will work fine. Before you start, you need to install two packages: debootstrap and some form of HTTP or FTP server. If you don't have a server installed, I recommend vsftpd.

For these instructions to work your Pro you must be running at least a 2.6.16 kernel, or else the chroot command will not work. I recommend using the latest upstream Linux kernel instead of a Buffalo or Marvell modified one; you can follow these instructions to install a recent one. It is a good idea to adjust the size of your partitions before following this procedure, as the /dev/sda2 partition is very small by default. I suggest making it at least 5 GB. You also need to be using a modified initrd in order to boot the custom distribution.

Create the Stage 1 image

On your Linux workstation, pick a directory that you will stage the Debian install in. For my example I will use /tmp/debian. Become root and use debootstrap to create a minimal Debian installation in this directory:

Unpack the image and complete the debootstrap process

Now boot your Pro in EM mode and telnet to it. I'm assuming that you want to overwrite the installed system on /dev/sda2. If that's not what you want, don't run the mkfs command. Instead, choose another directory to install to.

I use the ext3 filesystem for this example because it's very likely that your kernel has support for it. If you'd like to use a different filesystem, it's up to you to determine whether the kernel you're using supports it.

Make a new filesystem on /dev/sda2 and mount it. Download the tarball from your FTP server, and unpack the minimal Debian image. Then chroot into it and complete the bootstrap process:

The last step may take a while, but you now have a full Debian system installed on your Linkstation. Don't reboot yet, though... we don't have a working system!

Configure the system and install additional software

There are two files that need to be configured before the system will run correctly, /etc/fstab and /etc/network/interfaces. The first describes the layout of filesystems on your disk; the second, as the name implies, configures network interfaces.

After mounting the proc filesystem, you can use chroot to enter the system and modify the configuration files:

/srv is the location recommended by the FHS for data stored on the system by and for services such as FTP and Samba. Your partition may be formatted as XFS; if this is the case I recommend changing it to ext3, as XFS has known bugs on the ARM9 platform.

This /etc/network/interfaces will bring up the network device using DHCP.

auto lo eth0
iface lo inet loopback
iface eth0 inet dhcp

You also need to install micro_evtd, which keeps the watchdog timer in the LS Pro happy, adjusts the fan speed for you, and such. The binaries and configuration files for micro_evtd are provided by lb_worm and stored in the downloads area.

Note: This file should be treated with caution as the checksums below don't match either the archive, or any of the files contained in it. Unless the original poster fixes the file or the checksums it would be prudent to source the required files from the other links. However, the file uImage-2.6.26 within the tar archive does match the one linked above, so it may just be an cut & past error.

Once you have all of this.

Reboot / get into EM mode. I suggest you copy the files to another computer (so you can pick up the pieces). Rename the boot_options to the correct name, rename initrd.buff... to the correct name remove the link from the current kernel to the uImage2.6.26 (2.6.26 kernel).
mount /dev/sda2 untar the lenny armel tar / other file / files to it. extract the modules.tar / modules to /lib/modules (move to the appropriate place).

Reboot. And hope it works !
Oh and if you find that the linkstation is rebooting and beeping you can disable the watchdog microapl -a system_set_watchdog 255 . Others have reported that decreasing or turning off the polling will also fix the problem.
